In 1945, Charles and Ray Eames designed a toy elephant made of plywood. They found elephants to be be very charming, as depicted in many of their photographic works. The Plywood Elephant was intended to be played with by children, as exemplified by its curved edges. It was never mass-produced (only two models were made). In 2007, Vitra launched a limited anniversary edition of the Plywood Elephant. Vitra also manufactures a plastic version of the elephant made of dyed polypropylene with a matt surface finish, available in a variety of bright colors.
